自动将图像帧添加到拍摄的屏幕截图

问题描述

我想自动将图像帧添加到拍摄的屏幕截图中.这是我用来截取屏幕截图的代码.有任何想法将这张图片放在拍摄的屏幕快照上吗?

I would like to automatically add a image frame to a taken screenshot. Here´s the code I´m using to take the screenshot. Any Ideas to put this image around the taken screenshot?

为完整起见:我想给用户一个选项，可以在Twitter或Facebook上与该框架共享漂亮的屏幕截图.

For the completeness: I want to give the user a option to share this beautiful screenshot with it´s frame on Twitter or Facebook.

顺便说一句:那是我作为程序员的第一个应用程序，所以请给我完整的解决方案或教程以完成此操作...

BTW: That´s my first app as programmer, so please give me full solution or a tutorial to do this…

推荐答案

我在评论中提出的解决方案.

The solution I proposed in the comments.

- (UIImage *)screenShot {
    UIImage *frame = [UIImage imageNamed:@"frame"];

    UIGraphicsBeginImageContext(frame.size);
    CGContextRef ctx = UIGraphicsGetCurrentContext();
    [frame drawAtPoint:CGPointZero blendMode:kCGBlendModeOverlay alpha:1.0];

    CGContextTranslateCTM(ctx, xCordinateOfScreenshotInFrame, yCordinateOfScreenshotInFrame);
    [self.view.layer renderInContext:ctx];

    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return image;
}
